COTTON-GIN OF THE SAW TYPE.

To all whom it may concern:

Be it known that we, LELAND L. Foss and CHRISTIAN C. Foss, citizens of the United States, residing at Vidalia, in the county of Toombs, State of Georgia, have invented certain new and useful Improvements in COttOIlG111S of the Saw Type; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a cleaning and feeding device for gins of the saw type.

The primary object of the invention resides in the provision of means for separating the cotton from the stones or other foreign material before the cotton is fed to the saws.

A further object of the invention resides in so constructing the separating means that the cotton will not be retarded in its movement to the saws.

A still further object of the invention resides in the provision of novel actuating means for the separating means so that the speed of the latter may be varied in proportion to the speed of the picker roller.

With these and other objects in view, such as will appear as our description progresses, our invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

In the drawing: Figure 1 is a sectional view of a saw gin with our invention incorporated therein; Fig. 2 is a side elevation; Fig. 3 is a front elevation; Fig. 4 is a detail showing the driving means for the fan; Fig. 5 is a fragmental perspective view of the cotton deflector; Fig. 6 is a side elevation of the gin with a modified form of driving means incorporated therein; Fig. '7

is a fragmental sectional view on line 7-7 of Fig. 6; Fig. 8 is a vertical sectional view of a modified form of blower, and Fig. 9 is a similar viewtaken at right anglesto Fig. 8.

In the drawing we have illustrated a cotton gin of the saw type similar to the gin described in the co-pending application filed January 29, 1916, Serial No 75,064. Inasmuch as this is true it is not deemed necessary or advisable to enter into a detailed description of the structure of the gin and we will therefore describe only the improve- Specification of Letters Patent.

ments, referring to the gin as it becomes necessary. Mounted on the frame 1 of the gin is a hopper 2 in which a picker roller 3 is mounted on a shaft l. Cotton and foreign material are fed to the picker roller by the feed rollers 5 which are located above the picker roller. L In order that the cotton may be separated from foreign material and conveyed to the saw breast 6, we have provided a deflector which includes a pair of end pieces 7 having hooks 8 and 9 thereon and extending between these end pieces is a curved plate 10 which forms the cover of the deflector, the lower portion of the deflector being entirely open. Extending between the end pieces 7 and between the plate 10 and the lower edges of the end pieces is a guide plate 11 on which an auxiliary plate 12 is ad justably mounted, the plate 12 being held on the guide plate 11 by setscrews 13 which The deflector is supported by the engagement of the hooks 8 and 9 with pins 1 1' on the hop per 2 and pins 15 which are carried by braces 1.6. The lower open end of this deflector is directed toward the upper open end of the saw breast 6. It will thus be seen that the deflector may be readily removed and replaced when desired. I Mounted beneath the picker roller 3 is a fan casing 17 which extends throughout the entire length of the machine'and is provided with a nozzle 18 having its opening 19 directed toward the deflector above the edge of the plate 12. A fan 20 is mounted in this casing 17 and extends throughout the length of'the same so that a blast of air is directed from the opening 19 immediately beneath the lower edge of the cotton board 21 and above the upper edge of the plate 12. It will thus be seen that as the cotton is fed from the board 21 the blastfrom the opening 19 will strike the same and blow the cotton against the plate 10 from whence it will be fed by the assistance of the guide plate 11 to the breast 6. It is to be noted that the nozzle 18 is so directed that the movement and other heavy foreign material so that the stones will drop from the edge of the cotton board 21 and will therefore not pass to the bIBii-Si] 6- In order that the feed rollers 5, the picker roller 3 and the fan may be rotated in a certain definite ratio, I have secured a pulley 22 to the shaft 4, which pulley is actuated by a belt 23 passing over a pulley 24, which latter pulley is actuated by a belt 25 which passes to the power shaft. A friction disk 26 is secured to the end of the shaft 4 remote from the pulley 22 and a similar disk 27 is mounted on a stub shaft above the disk 26. Extending vertically and across the faces of the disks 26 and 27 is-a shaft 28 on which a friction wheel 29 is secured, which wheel is adapted to contact with the faceof the disk 26. This shaft is further provided with a friction wheel 30 which is SllClflblQ'OIl the shaft but rotatable therewith and which is adapted to contact with the friction disk 27. This shaft 28 is mounted in bearings carried by levers 31 which are hinged, at 32, and'are provided with screws 33. These screws act so that the friction wheels 29'and 30 may be drawn tightly into contact with or released from the disks 26 and 27 as will be readily understood. Now this shaft is slidable vertically in its bearings and its movement is controlled by a lever 34 which is operable on a rack 35 and is attached to the upper end of the shaft.

The friction wheel 30 is adjusted vertically on the shaft by means of a shipper lever 36 which is operable on a rack 37 Secured to' the stub shaft on which the disk 27 is mounted is a pinion 38 which meshes with a gear 39 carried by one of the feed rollers at one of its ends. The ends of the feed rollers remote from the last mentioned end are provided with intermeshing gears 40.

I Thus it will be seen that when the pulley 22 is actuated together with the disk 26 that the feed rollers will be actuated together with the picker roller 3. It will be further seen that by adjusting the friction wheel 30 to and away from the center of the disk 27 the speed of the feed rollers will be varied.

In order that the fan 20 may be driven, I have'provided one form of mechanism which is disclosed in Fig. 4 and which includes a gear .41 formed on the pulley 22 which meshes with a pinion 42 on the fan shaft. I have however provided a disk 43 which is secured to the fan shaft and with which a friction wheel 44, which is secured to the shaft 28, cooperates. It will be seen with this latter arrangement that when the lever 34 is actuated to move the shaft 28 upwardly, for instance, the friction wheel 29 will be moved away from the center of the disk 26 and the friction wheel 44 will be moved toward the center of the disk 43 so that the speed of the fan will be increased. Of course the reverse will be true when the lever is moved in the opposite direction. The stub shaft on which the disk 27 is mounted is indicated by the reference character 45 in Fig. 7 of the drawing and this shaft is slidable in a bearing 46, its movement being effected by a lever 47. The object of the sliding movement of this stub shaft is to permit the frictional engagement between the friction wheel 30 and the disk 27 to be varied independently of the variation by the lever 31.

Referring particularly to Figs. 8 and 9 of the drawing it will be seen that I have produced a modified form of fan casing and this form includes an elongated casing 48 which extends from end to end of the machine and the bottom 49 of which inclines upwardly toward the top. Extending from this casing 48 is a nozzle 50 which projects from end to end of the machine and is directed toward the deflector for the cotton. This casing 48 is not constructed to receive the fan but only to convey the air to the deflector from a fan located externally of the machine, which air is conveyed to the casing by any suitable conveyer 51, in which conveyer a plate or damper 52 is mounted, which may control the velocity of the air leaving the nozzle 50. n

While we have illustrated and described a particular embodiment of our invention, it has merely been for the sake of convenience and we do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the de tails of construction without departing from the spirit of the invention or exceeding the scope of the appended claims.
